Sure, there are good examples of this in other syntax
definitions.  Just grep the xml syntax definitions for

IncludeRules context="[^"]*##

For example in javascript.xml you'll find

      <context attribute="Comment" lineEndContext="#pop" name="Comment">
        <IncludeRules context="##Alerts" />
        <IncludeRules context="##Modelines" />
      </context>

and

    <context name="JS content" attribute="Other Text" lineEndContext="#stay">
      <RegExpr attribute="Element" context="El Close 2" String="&lt;/script\b" insensitive="true" endRegion="script" />
      <RegExpr attribute="Comment" context="JS comment close" String="//(?=.*&lt;/script\b)" insensitive="true" />
      <IncludeRules context="Normal##JavaScript" includeAttrib="true"/>
    </context>

That last one includes the Normal context from javascript.xml.
